I'm migrating to new large drives and would lke to take advantage of a filesystem that has integrated data and metadata checksums. How well does ZFS on Linux really work? What is the current status of BTRFS? Which one would you trust your precious data to? I've been out of the loop lately... This would be a great meeting topic! "How to set up ZFS on Linux and/or BTRFS". Any takers?
I wouldn't trust my data to btrfs, especially if you're using anything other than the default mkfs and mount options. But don't take my word for it, have a look through the btrfs mailing list archives[1]. I have no experience with zfs on linux, but I've heard that data checksums have a signficant performance impact. I don't have any data on that, so you should probably do your own benchmarking to verify things perform well enough for your workload. If I were you, I'd use xfs.
